Patented Jan. 14, 1930 UNITED STATES PATENT DFFlfiE WILLIAM F. HUCK, OF BROOKLYN, NEW YORK, ASSIGNOB TO B. HOE &, CO. INC., 015 NEW YORK, N. Y., A CORPORATION OF NEW YORK PROCESS AND APPARATUS FOR MATRIX ROLLiNG Application filed April 21,

This invention relates to matrix rolling machines having movable beds and a main pressure roll, and more particularly to means for mounting ironing out rollers at the side of the main pressure roll to bear on the work in advance or the main roll, though it is noted that the invention is not limited to use with the particular machine stated.

In making matrices for stereotype plates, a form is made up consisting of type locked in a chase. On this is placed the paper mat which is rolled into the type to take the impression and form a matrix. Over the mat are placed blankets of cork and felt. A frame thus covered is placed on the table of a matrix rolling machine and passed under the pressure roll thereof.

Unless means are taken to prevent it, the blankets will be forced back in the form of wave in front of the main pressure roll, and one object of the present invention is to pro vide efficient means to keep the blankets drawn taut in order to insure good work. Said means may be one or more ironing-out rollers or other pressure devices placed longitudinally of the main pressure roll, and another object of the invention is to provide in a device ofthis kind an eflicient arrangement for supporting said means.

Another ob ect of the invention is to provide in an apparatus of this kind eificient means for automatically raising the pressure devices for the mat and blankets to pass thereunder and lowering the devices to press upon the work to prevent said waves.

Another object of the invention is to provide a method and apparatus of this kind which is operative from either side of the main pressure roll and when the type moves in either direction.

Other objects are to provide adjustment for the pressure of the ironing-out rolls and means for limiting their movement.

Still other objects of the invention are to improve generally the simplicity and efiiciency of such devices and methods to provide a device of this kind which is economical, durable and reliable in operation, and economical to manufacture and install.

And still other objects of the invention will 1927. serial No. 185,561.

appear as the description proceeds; and while herein details of the invention are described and claimed, the invention is not limited to these, since many and various changes may be made without departing from the scope of the invention as claimed in the broader claims.

The inventive features for the accomplishment of these and other objects are shown herein in connection with an improved ironing-out device which, briefly stated, includes a pair of rings respectively frictionally engaged in grooves at each end of the main pressure roll of a matrix rolling machine having a slidable bed adapted to receive type over which is placed the mat and having the pressure roll above the bed. Each ring is provided with lower bearing lugs in which are received end journals of ironing-out rollers disposed at opposite sides of the roll, whereby when said roll is rotated one roller will press upon the work and leave the opposite roller raised ready to receive the next mat.

In the accompanying drawing showing by way of example one of many possible embodiments of the invention,

Fig. 1 is a transverse vertical sectional view, partly in elevation, showing a portion of the rolling machine and the pressure devices attached thereto, the section being taken approximately on the line 1-1 of Fig. 2, looking in the direction of the arrows of said line; I

Fig. 2 is a horizontal sectional view, partly in plan, showing the machine as in- Fig. 1, the device being shown in plan, the section being taken approximately on the line 2-2 of Fig.1, looking in the direction of the arrows of said line; and

Fig. 3 is a transverse vertical sectional view, partly in elevation, showing the main roll with ironing-out device attached, the section being taken on the line i 3 of Fig. 2, looking in the direction of the arrows of said line.

My improved device is shown-in combination with a matrix rolling machine compris ing a frame 5, a table or bed 6 horizontally slidable thereon, though it is noted that the invention is not limited to use with this particular machine. Bearing brackets 7 on the frame carry adjustable eccentric bearing bushings 8' (Fig. 2) therein supporting an upper main pressure roll 8 above the bed and having journals 9 carried in said bushings and having projecting ends 10 and 11.

A similar lower, pressure roll engaging un der the bed has journals journaled in the frame, said journals also having projecting ends. Intermeshing gears 15, 16 (Fig. 1) carried on the projecting ends 11 and a similar end directly beneath, cause the rolls to turn in unison in opposite directions; while a spur gear 18 on the projecting end 19 of the lower roll engages a rack 20 on the lower part of the bed, whereby the bed moves with the lowest part of the upper roll.

A vertical power shaft 21 carries a worm 22 thereon engaging and driving a worm wheel 23 on the projecting end 10, whereby said rolls may be rotated and said bed longitudinally moved back and forth.

A chase 25 with type locked therein rests on the bed, over which type is placed the paper mat 27 with cork and felt blankets 28 superposed thereon, which mat is rolled into the type by the rolls as the rolls are rotated and the bed moved, thereby to take an impression and form a matrix. Unless'means are taken to prevent it, the blankets will be forced back in the form of wave in front of the ro1ler8, and the main object of the pres ent ironing-out device is to provide means to keep the blankets drawn taut in order to insure good work. This device will now be described.

Each end of the upper roll 8 is provided with an annular groove 30 (Fig. 2) therearound in which is disposed a split ring 31,

a each comprising upper and lower sections 32,

33 (Figs. 2 and 3) respectively comprising end lugs 35, 36, the lower lugs having threaded openings, the upper lugs having unthreaded openings, in which are received screws 37 on which are disposed springs 38 between the screw heads and the upper lugs 35, whereby the rings are adjustably frictionally held in the grooves.

Bearing lugs 38 on the ends of each lower section 33 beneath the lug thereof are each provided with a bearing bore alined with the similar bore of the ring at the opposite end 'of the main roll 8, in which are received end journals 39 of pressure device such as ironing-out rollers 40, 41 disposed longitudinal- 1y of and at opposite sides of the upper roll 8, whereby when the main rolls are rotated and the bed moved, the rings will, because of the friction, initially turn and tend to rotate with, and in the direction of the upper roll, thereby to lower and press to the blanket, forinstance the roller 40 of Fig. '1 adjacent to the mat when the mat is moved, in the direction of the arrow 43, to the main roll, and leave the opposite roller 41 raised, on the side where the mat leaves the main roll, for the reception of the next mat, which may be inserted from that side.

Spaced stop lugs 43, 44 on the top of the mid part of the upper ring are adapted to engage a stop pin 45 mounted on each main bearing bracket 7 and disposed between said stop lugs, thereby to limit the motion of the rings to prevent either roll from coming too close to the bed. 7

While the herein invention is not limited to the particular rolling machine shown, suitable means are shown for adjustably rotating the eccentric bushings 8. This means comprises extension brackets 48 on the bearing brackets 7, each carrying an upwardly extending bearing bracket 49 and a head 50l1iLV- ing a vertical bore. An arm 51 carried on each bushing 8 has a transverse bearing opening at its end in which is disposed a cylindrical block 52 having a threaded bore. A screw 53 in the vertical bore of the head 50 has a threaded end in the threaded bore of the block 52 and carries abeveled gear 54 on its upper end. A synchronizing shaft 55 mounted in said upwardly extending bracket 49 carries intermediately thereof hand wheels 56, and gears 57 on the ends thereof engaging with said beveled gears, whereby said screws may be simultaneously turned and said bushings simultaneously adjusted.

A scale 60 is mounted on the end of each of the arms; and an upright 61 on the frame of the machine is provided with an index 62 cooperating with the scale for accurate adjustment of the arms, the bushings and the upper roll 8.

In operation, the form with blankets 28 thereon is placed on the table 6 and pushed in close to the roll 8. When the machine is started to move the bed in the direction of the arrow 43, the friction of rings 31 on roll 8 willcause roll 40 to be brought into contact '7 with the blankets and exert pressure which can be varied by adjusting the screws 37. The blanket is thus held taut and smooth as it enters under the roll 8. a

It should be noted that while the form is passing through the machine, the roll 40 is pressed down while the roll 41 is raised. When it is desired to roll another form, it can be placed on: the table which would then be on the oppositeside of the roll 8, the roller 41 being raised will not interfere with the placing of the form. Or, if preferred, the 7 machine can be reversed and the table 6 run back empty, and the next form can be rolledv from the same side of the machine as before. In this case, the backward motion of the table would raise the roll 40' and leave the machine ready to. insert the new form as before described, and in this case only one roller 40 or 41 is necessar though the invention is not thus limited.

I claim as my invention 1. In combination, a support means to receive type with a mat thereon; a pressure roll, said roll and means being relatively movable to press the mat to the type; pressing devices disposed at opposite sides of the roll; and means adjustably yieldably connected to said roll and supporting the devices whereby when said roll is rotated one device may move to the plane of the mat topress the mat to the type and remove the opposite device from said plane to leave it spaced therefrom.
